Successful Preservation Practices for Steel Bridge Coatings

The purpose of each scan, and of Project 20-68A as a whole, is to accelerate the integration of innovative ideas into practice by information sharing and technology exchange among State transportation agencies. This scan focuses on coatings and coating methods for steel highway bridges that extend service life and inhibit corrosion. The scan team used a Type 3 desk scan with a workshop that brought together practitioners from 11 State departments of transportation (DOTs) and two non-DOTs. The scan team and practitioners met in Orlando, Florida, during the week of May 22, 2016, and exchanged information using presentations, roundtable discussions, and webinars. The scan identified effective strategies and practices transportation agencies use in these areas: determination of agency funding levels, evaluation practices for in-situ coatings prior to recoating, surface preparation, coating option decision-making, use of performance-based contracts (i.e., warranties), performance evaluation of overcoat and replacement coatings, specifications for coating systems, quality assurance coating inspection requirements, quality control inspector qualifications, contractor qualifications, and agency commitment to supporting future preservation of coatings.
